Worlds That Outlived Their Sun sleep documentary, 2hours No Adverts

The first planets ever confirmed beyond the Sun circle a star that already died. Over two hours of quiet narration, no adverts. In February 1990, with its steering out of use for repairs, the Arecibo radio telescope could only stare straight up. Aleksander Wolszczan used the idle time to search for fast pulsars, and found one in Virgo, turning about 160 times a second. Its ticks kept arriving a little early and a little late. In January 1992 he and Dale Frail announced the reason in Nature: planets. Two of them, and in 1994 a third, the first worlds beyond the Sun ever confirmed. This is the fifth and last episode of Worlds That Should Not Exist. It follows the planet that was withdrawn in Atlanta, the three to two rhythm that proved these were real, how a clock learns the angle of an orbit, why the planets were made after their star died, the fourth world that turned out to be gas, the search for dust, eight hundred other pulsars, and the night the dish fell. We go slowly. A clock that ran slightly wrong, a telescope that could not turn, a room applauding a retraction, a university with Copernicus's name, a star that walks in circles at a snail's pace, and a patch of sky two fingers from the grape gatherer. There is nothing here you need to remember. No test at the end, nothing to stay awake for. Let it run, listen for as long as you like, and sleep through the rest. Measurement, consensus and conjecture are kept apart throughout. The planets' orbits and masses are measured; that they formed after the star died is the consensus reading; which disc made them is still argued, and the episode says so. The objection that these were not really the first worlds gets its own part at full strength.

None of it asks anything of you. Built for sleep: 2 hours 20 minutes of continuous narration, recorded quietly and mastered with no sudden peaks. The picture holds a dark palette and never cuts to bright. A soft chord bed fades to silence at the end rather than stopping, because an abrupt stop after two hours wakes people.
